I've had this puzzle for about half a year now and it's become my new favorite puzzle! I should note that I've solved over 150 twisty puzzles to date and own about 100 at the moment. Although I love all of my puzzles, and some of them I solve more frequently than others, there have been a few puzzles that I've gotten obsessed over throughout the years. The first puzzle I was hooked on was a regular 6x6 cube back in 2014. In 2016 I got hooked on the 4x4 Axis Cube. In 2017 I was hooked on the 4x4 Ghost Cube. In 2020 I was hooked on the Crazy 4x4 Circle Cube (Version III). All of those puzzles are still my favorites till this day. Now this Sidgman's 2x4x6 Brick Wall is the 5th puzzle to join this category of favorites, and since it's the most recent favorite, it takes the number 1 spot for now.

So, what do I love about this puzzle so much? Well, the first thing I love is that it's the perfect level of difficulty. It's difficult enough that most cubers would struggle to figure out how to solve it, but not so difficult that it would take you hours to solve it (once you've solved it a number of times and gotten the hang of it). You definitely need to be an experienced solver to tackle this puzzle. It's even-layered, it's an ultimate-shape-shifter cuboid, it bandages, it shape-shifts, and on top of that it's fishered. Combining all of these elements, it will really mess with your head for the first few solves, even if you're an advanced solver. But once you've done enough solves on it, it's possible to solve this puzzle in under 10 minutes. Seeing this puzzle go from the scrambled mess that it becomes to its solved state is very satisfying! Especially when you can pick it up and do a solve anytime in 10-15 minutes.

Second, I love that it utilizes a whole variety of algorithms, such as a variety of cuboid algorithms, the Red Bull algorithm, and some 2x2 algorithms. And these algorithms can be applied in unusual ways to this puzzle that adds to the fun.

Third, I love that the part of the solve where you get it back into its proper shape is very intuitive once you grasp what needs to be done -- but looks pretty intense and crazy to someone who doesn't understand how the puzzle works.

Fourth, I love the fact that it's ghosted in its solved state, which makes the solve all the more challenging, and also allows for a better scramble (since many of the colors must be separated from each other to be possible to scramble).

Fifth, love the fact that in its solved state it has the shape of a cuboid, but once scrambled the fisher extensions are the same height as the 6-layer sides, which gives the puzzle a sort of cubic shape in its scrambled state.

Sixth, I just love the overall look of the puzzle.

The stickers are of very good quality and since there are no tiny stickers on this puzzle, they've been holding up very well so far. I've done probably over 100 solves on it so far and the stickers still look the same as they did on day 1.

The only complaint I have about this puzzle is that the outer 6x6 layers tend to pop out a bit. They don't fully pop out (as in actually coming out of the puzzle), but rather pop out of place while still being in the puzzle, and you just have to pop them back in. This only happens when you turn those outer 6x6 layers and it can be a bit annoying, but you only need to turn those layers for maybe 10% of the solve, so it's not an issue for most of the solve.

All in all, I highly recommend this puzzle. Just bear in mind that you need to be able to solve a variety of other puzzles before tackling this one. Puzzles you should be able to solve include: 2x2 cube, 3x3 cube, 4x4 cube, 3x3 shape mods, preferably at least a few 4x4 shape mods (e.g. 4x4 fisher, 4x4 windmill, 4x4 axis, 4x4 megamorphic, etc.), at least some higher order cuboids (e.g. 3x3x4, 4x4x3, 3x3x5, 4x4x6, 2x4x6, etc.), and perhaps some experience with cutter cubes (e.g. fisher cutter, windmill cutter, etc.).

This is a nice puzzle that provides an interesting challenge. This looks very neat in the solved state and while solving. I agree with another reviewer that the outer layers pop out just a bit and it feels concerning each time but they have always just popped back in with slight pressure.
